    Why are online UPS more expensive than offline UPS with the same output?
    These units continuously convert incoming AC power to DC, and then back to AC. This double conversion process isolates connected equipment from all power fluctuations and disturbances, ensuring a clean and steady power output. While this technology provides unmatched protection, it also results in higher costs.Mar 12, 2024
